CHARLES C. TYLER, OF NEW YORK, N. Y.

PERCOLATOR FOR ROSIN.

SPECIFICATION forming part of Letters Patent No. 266,559, dated October24, 1882.

Application tiled September 527, 1882.

To all whom it may concern:

Be it known that I, OHARLEs C. TYLER, of the city and State of New York,have invented an Improvement in Percolators for Rosin, of which thefollowing is a specification.

In the manufacture of rosin it is usual to spread cotton-batting upon awire sieve at the bottom of a box and pour the melted rosin upon thesame, so as to strain it and retain any chips and foreign matter. Thesieve usually is made ofstrong wire with meshes, and it often happensthat the weight ot' the melted rosin, as it rests upon the layer ofcotton-batting, perforates the same at one or more places where it isnot supported by the wire ofthe sieve.

Myinvention is for strengthening the cotton pereolator, and preventingthesanie tearingand becoming perforated by the weight of melted rosin.

l malte use of a layer of cotton produced in any desired manner and ofthe proper width, and preferably in continuous web or sheet, so as to becut up in lengths to form rolls. Upon the under side of the cotton 1cause to adhere, by paste or other suitable cement, a layer of openwoven or knitted fabric having meshes of about aneighth of an inchmeasurement, (more or less,) and I preferably roll the percolator onaroller oi' wood, with two or more strips of paper between the la) ers,the fabric being outside. The percolator is then ready fortransportation. When applied to the sieve the roll of percolatingmaterial is laid down thereon at one end, and the strips of paper aredra-wn npwardly and the percolator unrolled to the proper extent tocover the sieve, and then it is cnt olf. In doing this the attendant isnot liable to injure the percolator, because his sticky hands do notnecessarily come into contact with the cotton, and the fabric beingbelow the fibrous layer prevents the material being injured by theweight of melted rosin poured in upon the percolator.

In the drawings, Figure l is a section of the percolator and sieve, andFig. 2 represents the roll of material for the percolator.

The layer of cotton a has cemented upon its under side the fabric b, ofwoven or knitted material, the same heilig of a very open mesh.

(No model.)

This forms the percolator, and it is Wound upon the roller d forconvenience of handling, the strips of paper c being rolled in betweenthe layers of the percolator to aid in unrolling the same.

h represents the box portion ofthe percolator, and k the sieve-bottomsupporting the cotton percolator.

Z is the receptacle for the filtered rosin.

Vhen the percolator becomes covered with chips and pieces of foreignsubstances, so as to be no longer serviceable, the same is raked off andremoved and a new percolator applied.

I remark that this percolator is much more durable than the battingheretofore employed, land can be much thinner and equally effective,because the fabric furnishes the strength required for supporting.;` thecotton, and this percolator, being thin, allows the rosin to run-through freely and rapidly; but the foreign materials are retained.

vA woven or knitted fabric may be cemented upon both sides of the layerof cotton, so that the percolator may be used either side up, and thestrength is thereby increased. The 'percolator may be eut up intosquares of the proper size for the sieves.

l claim as my invention- 1. The combination, with the metal sieve in arosin-percolator, of a layer of cotton with a woven or knitted fabricupon its under side next to the sieve, substantially as and for thepurposes set forth.

2. The percolator for rosin, formed of a layer ofcolton with a fabriccemented to one side. and rolled upon a roller, with strips of paperintervening between the layers, for the purposes and as set forth.

3. The percolator for rosin, formed ofa layer of cotton with a fabricattached to one or both of its surfaces, substantially as and for thepurposes set forth.

Signed by me this 25th day of September, A. D. 1882.
